As more minerals are extracted, the use of water increases, leading to greater wastewater and tailings production. To tackle this issue, flocculants are commonly used across mining sites to dewater waste streams by binding and settling particles, to allow for improved solid-liquid separation. While conventional flocculants (synthetic polymers often derived from petrochemicals) are effective in rapidly settling particles, they present several issues, such as high levels of entrapped water, ineffective fine particle separation, and environmental and health concerns. To address these challenges, bioflocculants have been proposed as alternative flocculants. This review explores three main bioflocculant research directions, including plant based, graft copolymers, and microbial flocculants, discussing the advantages and disadvantages of each. The ratio of flocculant dose to suspended solids (i.e. flocculant dose ratio) and the flocculation efficiency in these studies related to mineral and mining wastewater solid-liquid separation are evaluated. Finally, the review proposes future opportunities and directions to mitigate issues that have historically made bioflocculants less appealing. These include enhancing the recyclability of flocculants as well as advancing protein design and modification.</p></div>","PeriodicalId":18322,"journal":{"name":"Materials Today Sustainability","volume":"28 ","pages":"Article 100965"},"PeriodicalIF":7.1,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2589234724003014/pdfft?md5=3561de6f3a4a09b6c5fbf5a7f6b8e858&pid=1-s2.0-S2589234724003014-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142122871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Supercapacitors have recently become a more desirable alternative due to their quick charging and discharging times, high power densities, and extended cycle lives. For many researchers, improving supercapacitor efficiency for multifunctional applications is a major area of study. Many elements have been employed as electrode materials to provide the best energy and power density while achieving the largest specific capacitance. Among these materials, 2D transition metal carbides and nitrides, commonly called MXenes, are emerging candidates, particularly in electrochemical energy storage applications. Because of their strength, flexibility, unique structure, increased electrical conductivity, large surface area, diversity of active sites, hydrophobicity, and hydrophilicity for cutting-edge energy storage technologies, MXenes are among the best active electrode materials. MXene, with its unique 2D layered structure, offers the infinite possibility of the intercalation of various capacitive materials. Also, MXenes have the properties of high hydrophilicity of metal oxides and high electrical conductivity of metals. Alongside, activated carbon (AC), graphene, carbon nanotubes (CNTs), transition metal oxides, and conducting polymers (CPs) act as excellent electrode materials owing to their outstanding thermal, mechanical, electrical, and morphological properties. According to recent studies, one of the perfect methods for energy storage applications is to integrate MXenes with other superior elements for generating MXene-based composite electrode materials. This review includes recent developments in the investigation of MXene-based hybrid composites for supercapacitors.

For this purpose, a flower-like cadmium selenide (CdSe nanoflower), as a new promising NIR-activated photocatalyst, was synthesized through a hydrothermal process and characterized using various spectroscopic and microscopic analytical techniques. The characterization results indicated that CdSe nanoflower is classified as an n-type semiconductor with a direct band gap of 1.7 eV (<em>i.e.</em>, E_CB = −0.7 V and E_VB = 1 V indicated by Mott-Schottky analysis), and crystallite size and strain of 9.17 nm and 2.14, respectively. In the presence of various scavengers, the production of reactive oxygen species decreases, resulting in lower degradation efficiency. To investigate the photocatalytic efficacy, sulfamethoxazole (SMX) was used as a model pollutant drug molecule. The optimization of the process revealed that over 98% of SMX could be degraded under NIR irradiation and optimal conditions (pH = 7, photocatalyst dosage = 0.1 g, SMX concentration = 40 mg/L, time = 60 min), where Lagergren model with a correlation coefficient of 0.9765 was the best kinetic model describing the empirical results. The study indicates that CdSe nanoflower can be reused and regenerated up to 7 times with a 12% decrease in performance and after 60 min of degradation, the TOC concentration decreased by 81% in the best conditions. Additionally, CdSe nanoflower showed photodynamic microbial inactivation efficacy against <em>Escherichia coli</em> (<em>E. coli</em>) and <em>Staphylococcus aureus</em> (<em>S. aureus</em>) under NIR light irradiation, where almost 95 and 99 % of bacteria was reduced in 20 min.

This study analyzed the microstructure of 6061 alloy after undergoing severe plastic deformation under various processing conditions followed by T6 homogenization heat treatment. Utilizing a white light interferometer, a comparative analysis of the surface roughness was conducted on specimens that underwent single-point diamond turning to achieve a mirror finish. The assessment of surface roughness on machined surfaces is solely based on white light interferometry. The analysis and discussion focus on the effects of phases (causing scratches and voids), the grains and grain boundaries. Experimental findings signify: the grain size, grain boundary and residual second phase can both influence the surface quality, the increase in deformation temperature and accumulated strain both facilitate the dissolution and fragmentation of the secondary phases. However, they also contribute to some extent to grain growth, resulting in a minimum secondary phase area fraction of 0.87% and grain sizes reaching 147.8 μm. Subsequent heat treatments, while effective in reducing the negative impact of the phases, reveal noticeable step-like structures affecting the quality of surface roughness, with the lowest obtained Ra value being 0.8 nm.

Currently existing studies focussed on the influence of usage of bagasse ash in binary blended concrete, however a comprehensive review on the utilization of bagasse ash in binary, ternary, and quaternary blended concrete is highly limited. Therefore, this study provides a systematic review of the synergistic use of bagasse ash with other potential supplementary materials to produce bagasse ash-based binary, ternary, and quaternary blended concrete.

Results indicate that binary concrete with bagasse ash demonstrates a 10%–20% increase in compressive strength compared to reference concrete at an optimal replacement level of 20%. In ternary and quaternary blends, cement can be replaced by up to 40% without compromising strength. Notably, ternary blends incorporating bagasse ash with materials such as palm oil fuel ash or rice husk ash exhibit enhanced strength and durability properties.
